"Shade is supposed to be the enemy of a farm.

@Boerps Weil es z.B. in Norddeutschland für viele Pflanzen draußen einfach zu kalt und zu nass ist. Da nimmt man dann auch in Kauf, dass die Lichttransmission von Plastikfolien etwas geringer ist als die von Glas, weil Plastik so viel billiger ist.

Auch. Aber auch zum Beschatten. Und da kann man auch gut Solarzellen nehmen. Drunter ist die Belüftung sogar noch besser. -

Das gibt Schattennetze für Folientunnel und in Zukunft werden die bestimmt auch wichtiger. Meine Tunnel sind diesen Sommer teilweise auch überheizt.
Aber Phoenix/Arizona hat ziemlich genau die doppelte Globalstrahlung wie Berlin. Es kommt also von der Sonne doppelt so viel Energie pro Quadratmeter an.
Wie einige Vortrötende geschrieben haben, es kommt völlig auf das örtliche Klima an, ob man mehr oder weniger Licht braucht.

In diesem Newsartikel war man sehr verwundert, dass unter Solarzellen etwas wächst. Warum nicht. IMHO benutzen Hopfenbauern in Bayern Solarzellen auch als Schattierung. Und Hopfen ist keine kleine Pflanze.Offensichtlich ist diese Technik noch nicht sehr verbreitet.

"Shade is supposed to be the enemy of a farm. Crops chase sunlight, so roofing a field with panels ought to starve them. Yet plot after plot came in with more fruit, not less, and the plants looked healthier than the ones baking in the open. Stranger still, the shaded rows did it while drinking far less water. (...) Chiltepin pepper plants produced three times as much fruit as those grown in full sun. Jalapenos matched their usual harvest while using 65 percent less water. Tomatoes grown under the array came in at twice the normal yield."
Good luck achieving that with a nuclear reactor.

@antanicus I could do that with a nuclear reactor, a random number generator, and a bunch of wooden boards, though.

Pilot projects in Southern Germany have shown similar effects with apple orchards. It has become too hot and sunny for the types of apples traditionally grown in the region.
Another topic for growing apples is hail, which can destroy the fruits. Solar panels also provide protection against hail. (Well, until the hailstorms get so desastrous that they also kill solar panels, okay.)
@nielso @antanicus Do you happen to have a few links handy? I had this topic with someone around the bodensee

@antanicus @paulschoe farmers did not know?
It is just the science about plants that has shown that for a long time. Well known scientific facts.

@antanicus No one could have foreseen that! Why doesn’t Trump just issue a decree to change the laws of nature?
Next on his list: remove all solarpanels.

@schnitzer @nielso @antanicus Links would be much appreciated, this may be relevant for our farm as well in the future. Wait, I noticed one or two links when I scroll all the way down.

@antanicus This reminds me a bit of fruit walls, the technique that northern Europeans used in the 17th century to create teeny microclimates for a specific crop: https://solar.lowtechmagazine.com/2015/12/fruit-walls-urban-farming-in-the-1600s/
I first learned about those at the Brooklyn Botanic Garden; they have examples of that espalier pruning technique in their collection.
They still exist in various ways with differences in different countries.

@antanicus Agrivoltaics is a rare win-win: solar panels cut thermal stress and evaporation while generating clean power. Doubling crop yields on 65% less water completely shatters the "food vs. energy" soil conflict. Decentralized, multi-use infrastructure beats single-purpose energy plants every time.

“Shade is supposed to be the enemy of a farm”
I thought that the fact that some plants thrive in the sunlight and some thrive in the shade was pretty much obviously known
And that at least farmers would know that which plants are which depend both on the plant and the location / climate where you're trying to grow them
And that the non obvious bit that requires nontrivial experiments is actually finding out which ones are which in the various places in a changing climate

@antanicus I'm thinking back to the book I read last year, and wondering what that means for the LER. Could it be higher than 2?
